Fig. 269.— The Kallikak famib 



Of the 480 descendants, in five 

 generations, of this branch, 143 are 

 known to have been feeble-minded, 

 36 illegitimate, 33 sexually immoral — 

 mostly prostitutes, 24 alcoholic, 3 

 epileptic, and 3 criminal. 82 died 

 in infancy. 



Of the 496 descendants, in five 

 generations, of this branch, none were 

 feeble-minded, and all but 2 were nor- 

 mal mentally. 2 were alcoholic and 15 

 died in infancy. Thus nearly all were 

 good citizens. Among them were edu- 

 cators, physicians, lawyers, judges, 

 traders, landowners — men and women 

 prominent in every phase of social life. 

 (After Goddard.)
